  • Dietary Treatment Study of Fat Synthesis and Risk of Cardiovascular Disease

    open to eligible people ages 20-65

    The purpose of this study is to find out how the amount of fat or sugar in a person's diet, or the number of meals eaten each day, affect the amount of fat that people's bodies make, the types of fats in the bloodstream, and how much fat is stored in the liver. The study is funded by the National Institutes of Health.

  • Endoscopic Surgery for Bariatric Revision After Weight Loss Failure

    open to eligible people ages 18 years and up

    Morbid obesity and its associated metabolic diseases are on the rise in the United States. Currently, the best treatment for obesity is bariatric surgery where both roux-en-Y gastric bypass and sleeve gastrectomy offer substantial weight loss. Unfortunately, 20% of patients who undergo bariatric surgery fail to lose enough weight defined as less than 50% of excess body weight loss or regain of weight. For those patients who fail to lose weight after bariatric surgery and have failed maximal medical therapy and diet supervision, the treatment is re-operation and revision. Re-operation of the abdomen carries significant postoperative morbidity and mortality. The investigators propose to use the Apollo OverStitch endoscopic suturing device that has already been approved by the FDA as an option for bariatric surgery revision without having to re-operate on the patient. The investigators believe that the endoscopic technique may be able to provide weight loss without having to re-operate on the patient.

  • Inflammation, Diabetes, Ethnicity and Obesity Cohort

    open to eligible people ages 25-65

    Obesity affects over one third of US adults (>72 million, with BMI ≥30 kg/m2), and the proportion of US adults with BMI ≥40 kg/m2 has doubled in the last 20 years. Obesity is associated with increased mortality through its linkage to comorbidities including diabetes, hypertension, dyslipidemia, osteoarthritis, sleep apnea and psychosocial disturbances. Given its prevalence, impact on morbidity and mortality, and economic cost, limiting the spread of obesity and its consequences is one of the most important problems of our time. In this proposed study, investigators will recruit subjects from a wide range of body mass index (BMI), ethnicity and Diabetes risk to collect data and blood, stool and adipose tissue samples in the San Francisco bay area.

  • Pediatric Obesity Weight Evaluation Registry (POWER) Study

    open to eligible people ages up to 18 years

    The main objective of this study is to establish a national pediatric obesity registry known as POWER (Pediatric Obesity Weight Evaluation Registry). This registry will contain clinical data from individual comprehensive pediatric weight management programs around the United States for overweight and obese youth.

  • School Water Access, Food and Beverage Intake, and Obesity

    open to eligible people ages 9-12

    It is widely argued that the promotion of water consumption, as an alternative to sugar-sweetened beverages, can assist in childhood obesity prevention efforts. Yet no studies have tested this argument in real world schools where flavored milk or juices are available. This trial will fill gaps by examining how promoting fresh water intake-both in schools that do and do not provide access to caloric beverages -impacts children's consumption of food and beverages both during and outside of school, and obesity.

  • SCOPE-Chinese Women Study

    open to eligible females ages 18 years and up

    This project examines the feasibility of a smartphone-based intervention to reduce obesity and breast cancer risk among Chinese women in China. The proposed intervention is to use the mobile application and an activity tracker device to promote a healthier lifestyle and physical activity. The intervention will be tailored to the participants' behaviors, personal needs, and preferences. The aim is to reduce abdominal obesity and improve healthy lifestyle behaviors in premenopausal women with children in order to reduce the growing cancer burden in China.

  • A Mobile Health Intervention to Reduce Sweet Beverage Consumption in Latino Children

    Sorry, not yet accepting patients

    Sugar-sweetened beverage consumption is a major contributor to childhood obesity, caries, fatty liver disease, and Type 2 diabetes. Latino children are more likely to consume sugar-sweetened beverages (SSBs) and to suffer from all of the aforementioned conditions. Reading out loud to children from birth through age 5 is critical for the promotion of language and early literacy skills. Children whose parents read aloud to them are more likely to start school with the skills required for early reading success. This is important as reading proficiency in third grade is the best predictor of high school graduation and career success. Latino children are less likely to be read to than non-Hispanic white children and at higher risk of entering kindergarten without critical early literacy skills. Thus, there is a pressing need for interventions to reduce SSB consumption among Latino children as well as interventions that promote reading out loud. Primary care is an optimal setting for such interventions. However, multiple demands on providers' time make it difficult to rely on in-person interventions. For this reason, it is critical to test intervention designs that do not rely directly on health care providers and that can be delivered remotely if needed. The investigators have developed two m-health interventions for Latino parents, one that promotes optimal beverage consumption patterns and one that promotes reading out loud to children. The purpose of this study is to test the impact of these interventions on child beverage intake patterns and the frequency with which parents read to children.

  • Effects of Sleeve Gastrectomy on Calcium Metabolism and the Skeleton

    Sorry, in progress, not accepting new patients

    In this pre-post observational study, the investigators will enroll and follow a cohort of about 50 adults undergoing sleeve gastrectomy surgery for weight loss. Pre-operatively and at 6 and 12 months post-operatively, the investigators will use state-of-the-art metabolic and imaging techniques to evaluate calcium metabolism and skeletal health. Specific outcomes include intestinal calcium absorption capacity, bone mineral density (BMD) assessed by dual-energy X-ray absorptiometry (DXA) and quantitative computed tomography (QCT), and bone structure assessed by QCT and high-resolution peripheral QCT (HR-pQCT).

  • Evaluation of the Impact of Water Access and Promotion in Parks on Beverage Intake

    Sorry, in progress, not accepting new patients

    Sugar-sweetened beverages (SSBs) are a major caloric source and the largest source of added sugars in the American diet. While many cities around the country have adopted anti-SSB policies such as soda taxes to reduce SSB intake, there has yet to be any studies to evaluate if the effects of these taxes, coupled with increased water access and promotion effort can lead to decreased sugar sweetened beverage consumption and increased water consumption. This quasi-experimental study evaluates how implementation of SSB taxes, installation of new water stations, and a multicultural water promotion campaign in parks impacts beverage intake in these settings as compared to soda taxes alone.

  • GERD Following Laparoscopic Sleeve Gastrectomy

    Sorry, not yet accepting patients

    Laparoscopic Sleeve Gastrectomy (LSG) creates a vertical gastrectomy which results in a narrow and tubular shape of stomach. The line of resection starts at 3-6 cm. from pylorus (antrum) toward to the angle of His. The gastric antrum plays a major role in gastric emptying, particularly for solids. Hence, depending upon the starting point of gastric sleeve resection in each center, this can result in difference of the remaining gastric antrum which may affect gastric emptying time after this procedure.

  • ObeSity and Jobs in SoCioeconomically Disadvantaged CommUnities: A Randomized CLinical Precision Public HealTh Intervention --The SCULPT-Job Study

    Sorry, accepting new patients by invitation only

    This is an interventional research study about clinical, psychosocial, and behavioral factors that impact weight loss, weight maintenance, and cardiovascular disease in socially disadvantaged persons.

  • Strong Futures: A Trial of Two Primary Care Based Interventions to Promote Optimal Health in Latino Infants and Toddlers

    Sorry, in progress, not accepting new patients

    Latino children experience higher rates of obesity compared to non-Hispanic white children, especially in low-income communities. Optimal feeding strategies in early life, avoidance of screen time and longer sleep duration may lower the risk of obesity. Family financial hardship is also associated with short- and long-term health risks, including behavioral and mental health problems, and toxic stress which contributes to elevated risk of common chronic conditions over the life course. This proposal aims to pilot test two interventions to promote optimal health outcomes in Latino infants. Study participants will meet with a health educator after well child visits at 2-weeks, 2-, 4-, 6-, 9- and 12-months. Half of the parents will receive education on obesity prevention. The other half will receive financial education and case management using an established financial coaching approach. Parents will also receive text messages that reinforce educational content. The objective of this study is to determine the acceptability and feasibility of offering these interventions in the well-child setting. Study investigators also seek to determine the preliminary efficacy of these interventions on infant and parent health outcomes including dietary intake, screen time, sleep duration, health related quality of life and financial stress.
